Impale, on the point, the fruit (5)
I believe the answer is:
spear
'impale' is the definition.
(spearing is a kind of impaling)
'on the point the fruit' is the wordplay.
'on' is a charade indicator (letters next to each other).
'the point' becomes 'S' (South).
'the fruit' becomes 'pear' (pear is a kind of fruit).
's' put next to 'pear' is 'SPEAR'.
(Other definitions for spear that I've seen before include "Old weapon" , "Sharp-tipped weapon" , "Weapon to throw" , "Primitive weapon" , "asparagus for example" .)
